[TenTec] Slash 0

For those of you who insist on the <ALT>-0216 slash zero for every day purposes, PLEASE DON'T!  It may "look" good for you, but it can cause some problems...

1.  It's an extended ASCII character; therefore, it requires a font that maps char #216 to a slashed zero.  Not all fonts have a slashed zero as char #216.  Although *you* might see the slash zero when you type a message, the receiving end may not have a font that has a slash zero as ASCII 216 - instead, the message will display some other character that's mapped to #216 and this can make the message confusing.  For reference, ASCII characters above #127 are considered "extended".

2.  It doesn't sort as a true zero.  A true zero is ASCII char #48 (30h) - if you try to sort on an "extended" character slash zero, it won't sort as expected - especially if you have a mix of true zeros with the extended slash zero.  Char #216 will sort *after* the lower-case "z".

3.  It requires application support.  Not all apps support entering or displaying extended ASCII characters.  Browser based (aka web-based) apps (such as webmail) generally don't support entering extended ASCII characters.  Some may even not display the extended characters.


If you really wish to have a slash zero for day-to-day use, please use a font that has a slash zero as the "true" zero (ASCII char #48 (30h)).  Yes, this will not show a slash zero if you use a different font, but you won't run into any sorting, entry, or display problems.

Sorry for the rant...just trying to prevent future headaches.

Composing this email with Mozilla Thunderbird and Alt 0216 gives Ø. The 
Num Lock must be on, and if you want repeated slashed zeros " ØØØ " you 
must release the Alt key between 0216s.

Thanks for the information. I wonder if I can "remap" my regular zero 
key to do this with a single keystroke.
